Do I need sunscreen with more than 30 SPF?

Short answer: No

Sunscreens with an SPF (sun protection factor) of 30 block about 97% of ultraviolet rays, while sunscreens with an SPF of higher than 30 block 97%-98%.

It's more important that you choose "broad-spectrum" sunscreen, meaning it protects against both UVB and UVA rays. Sunbathers also need to apply a generous amount of sunscreen in order to get the full benefit of the SPF.

Is drinking fruit juice as good for you as eating fruit?

Short answer: No
Calorie for calorie, whole fruit provides more nutritional benefits than drinking the pure juice of that fruit. That's because when you liquefy fruit, stripping away the peel and dumping the pulp, many ingredients like fiber, calcium, vitamin C, and other antioxidants are lost.
For comparison, a five-ounce glass of orange juice that contains 69 calories has .3 grams of dietary fiber and 16 milligrams of calcium, whereas an orange with the same number of calories packs 3.1 grams of fiber and 60 milligrams of calcium.

Does olive oil prevent heart disease?

Short answer: Yes

The health benefits of olive oil come from the presence of polyphenols, antioxidants that reduce the risk of heart diseases and cancers.

But to get these healthy compounds, consumers should buy good-quality, fresh "extra-virgin" olive oil, which has the highest polyphenol content. Most commercially available olive oils have low levels of polyphenols associated with poor harvesting methods, improper storage, and heavy processing. 

Is walking as effective as running?

Short answer: Yes

Studies have shown that how long you exercise — and thus how many calories you burn — is more important than how hard you exercise. Running is a more efficient form of exercise, but not necessarily better for you.

A six-year study published in the journal Arteriosclerosis, Thrombosis, and Vascular Biology in April found that walking at a moderate pace and running produced similar health benefits, so long as the same amount of energy was expended.

Do nuts make you fat?

Short answer: No
As much as 75% of a nut is fat. But eating fat doesn't necessarily make you fat. The bigger factor leading to weight gain is portion-size. Luckily, nuts are loaded with healthy fats that keep you full. They're also a good source of protein and fiber.
One study even found that whole almonds have 20% less calories than previously thought because a lot of the fat is excreted from the body.

Do sugary soft drinks lead to diabetes?

Short answer: Yes

The majority of health research is stacked against sugar-sweetened soda. A large 2004 study in the Journal of the American Medical Association found that women who drank one or more sugary drinks per day increased their risk of developing type 2 diabetes by 83% compared to those who consumed less than one of these beverages per month.

WHO GETS TO BE AN MXA TEST RIDER?

There are three levels of MXA test rider: (1) In house; (2) MXA Race Team; (3) Photo Session. 

"In house" test riders have been testing bikes for years. They have ridden virtually every bike made, including factory works bikes and high-dollar exotics. These are the most experienced test riders in the world, because unlike manufacturers test riders, they aren't bound to one brand or one engine size. No MXA test bike is evaluated by any single rider but will be ridden by Jody Weisel, John Basher, Dennis Stapleton, Alan Olson and Willy Musgrave before it is handed down to the next tier of test riders--the MXA race team.

The "MXA race team" races every week and can normally be found at Glen Helen, Cahuilla Creek, Piru, Gorman or Competitive Edge. MXA race team members get free bikes, parts, clothes, helmets, maintenance and tires. But, they have to race a different bike every week, sometimes a different bike between motos. Their job is to accumulate a vast reservoir of information about each test bike in a short period of time. Its not unusual for one test bike to be ridden in four different classes on the same day.

The "Photo Session" riders ride the bikes for magazine photography. Many famous riders have spent time before the MXA cameras, the best known being Jeremy McGrath, but Mike Craig, Mike Chamberlain, Lance Moorewood, Clark Jones, Larry Brooks, Jeff Ward, Greg Schnell and Phil Lawrence have done the deed.
